Advanced Optical Solutions with Precision Micro Prisms

Shanghai Optics is at the forefront of developing micro prisms, which, despite being invisible to the naked eye, are essential for numerous modern technologies. These prisms, crafted from high-precision prism glass, facilitate the bending of light, contributing to the miniaturization and lightweighting of optical devices. Our advanced manufacturing techniques produce ultra-small micro prisms (under 3 mm) tailored for various applications and environments. The production process includes meticulous cutting, grinding, polishing, and coating, ensuring superior performance and longevity. Shanghai Optics offers both coated and uncoated micro prisms, including Penta and right-angle types, designed for diverse light deviation requirements. Enhanced with coatings like AR and bandpass filters, these prisms serve as effective beam splitters or light modifiers across UV, visible, and IR wavelengths.

Essential Role of Micro Prisms

Micro prisms, though tiny, are critical to the progress of various industries, including information communication. They play a significant role in making optical equipment smaller and lighter, thereby enhancing functionality and efficiency.

Customized Precision

At Shanghai Optics, we specialize in creating micro prisms with precision to meet specific customer needs. These prisms, made from high-quality prism glass, can manipulate light to transmit or reflect specific wavelengths. Our technology enables the production of ultra-small prisms, less than 3 mm in diameter, designed for various conditions, helping clients achieve their technical objectives.

The performance of micro prisms depends heavily on their production process, which involves:

    1. Cutting and Grinding: Shaping the optical glass to precise dimensions.
    2. Polishing: Achieving the desired surface quality.
    3. Coating: Applying specialized coatings for enhanced performance.
    4. Inspection: Ensuring defect-free products.


Micro Prism Varieties

We offer a range of micro prisms, each customizable to meet specific requirements:

Penta Prisms

  • Design: Pentagon-shaped with seven faces.
  • Function: Consistently deviates light by 90 degrees, irrespective of light entry point.
  • Materials: Manufactured from substrates like BK7 Grade-A optical glass, Corning Fused Silica 7980, JGS1, and JGS2.

Right-Angle Prisms

  • Design: Right triangle with two triangular faces and three rectangular faces.
  • Function: Deviates light by 90 or 180 degrees, depending on the light’s entry face.
  • Bevel Range: 0.1 to 0.2 mm.


Advanced Coatings

We apply various coatings, such as anti-reflection (AR) coatings and bandpass filters, to enhance the functionality of these prisms. These coatings allow the prisms to act as beam splitters or light modifiers, suitable for UV, visible, and IR wavelengths. Despite different shapes, all micro prisms share common properties like reflectivity, surface quality, and working wavelength.
